Hardware Servicing

The following topics contain information about service procedures for control enclosures.

This section describes removing and replacing field-replaceable units (FRUs) from the control enclosures.

Each part has its own removal procedure. Sometimes a step within a procedure refers you to a different remove or replace procedure. Complete the new procedure before you continue with the first procedure that you started.

Note: Do not use FRUs from containers with broken seals or try to transfer FRUs between systems. If you open a FRU container but do not use the part, do not re-seal the container; instead, send the FRU back for reconditioning per the Certified Service Parts (CSP) process.
